The International Film Series on the University of Colorado’s Boulder campus, at a remarkable 75 years of age, continues to attract serious film buffs and film students with nearly 60 films almost every evening between now and Dec. 5. It’s not meant for the casual movie-goer who is attracted by stadium seating and super-sized popcorn. Rather, it shows an ambitious schedule of obscure, foreign, experimental and art films. The price is right — $5 or $8 per entry, or 10 films for $50. Students pay less, and a handful are FREE. Click on the series site for screening times, locations and costs.
